A wad of paper is dropped from a second-story balcony and falls through still air to the ground.
As it speeds up, what happens to the air resistance it encounters?
answer/question/discussion: ->->->->->->->->->->->-> :
As speed increases, so does the air resistance.

What happens to the net force acting on it?
answer/question/discussion: ->->->->->->->->->->->-> :
The net force will still increase downward, but at a slower rate.
@& The net force would stay the same, F = m g, if there was no air resistance.
Air resistance acts in the direction opposite gravity, and is increasing.*@
#$&*
What happens to its acceleration?
answer/question/discussion: ->->->->->->->->->->->-> :
It will continue to accelerate until it reaches terminal velocity. It will accelerate at a slower rate than gravity though.
#$&*
If it dropped from a much higher point, what would happen to the net force and the acceleration?
answer/question/discussion: ->->->->->->->->->->->-> :
Both would remain the same, but the wad would reach terminal velocity at a higher position.
